Problems with Iphone 12pro, operating in speaker phone. The reception keeps braking up

Hi papapete46,

We understand you're unable to clearly hear people on speakerphone. We're happy to help.

If the speaker sound is not clear, we'd recommend trying these steps: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker

We'd also suggest testing the speaker audio with other apps to see if the issue occurs with all audio, or if it's just specific to call audio.

If you continue to have issues, you'd want to contact Apple Support directly for assistance: Get Support

We hope this helps. Take care!
